ROTARY MEASURlNG-FAUCET.

SPECIFICATION forming part of Letters Patent No. 229,592, dated July 6, 1880.

Application filed January 15, 1879.

To all whom it may concern:

Be it known that I, DANIEL DRAWBAUGH, of Eberlys Mill, in the county of Cumberland and -State of Pennsylvania, have invented cer- 5 tain new and useful Improvements in Rotary Measuring-Faucets; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of 1o this specification, in which- Figure 1 represents a View of the improved faucet, partlyin longitudinal section and partly in elevation; Fig. 2, a view of the faucet, looking from the rear 5 Fig. 3, a sectional view r 5 taken through the measuring-chamber and cutoff, and showin g therotary piston in elevation; Fig. 4, a view of the rotary piston detached; and Fig. 5, a detailed View of the actuatingshaft with its crank-pin or wrist, upon which zo the rotary piston is mounted.

Similar letters of reference in the several figures denote the same parts.

This invention relates to improvements in that class of faucets which are designed to draw oil, molasses, or other liquid from a cash or other reservoir in measured quantities; and it has for its objectl to improve the construction of such faucets and render them more perfect and reliable in their operation.

3o To this end the invention consists, primarily, of a faucet having a circular chamber provided with inlet and outlet ports, a cylindrical piston arranged within the chamber and mounted on an eccentrically-rotating axis, so as to be made to slide in contact with the circumferential wall of the chamber, and a fixed positive cut-oft' located between the inlet and outlet ports and extending into a recess in the rotating piston, for preventing the exit of the 40 liquid except when carried around and regularly discharged by the rotating piston.

It further consists in mounting the rotating piston upon the wrist of a crank or crank-disk attached to the actuating-shaft; and it con- 4 5 sists, lastly, in recessing the crank-disk in the side wall of the measuring-chamber, so that it will be iiush with the face of said side wall, and thus form a tight joint with the rotary piston.

In the drawings the casing of the faucet is 5o represented as being formed in two parts, the letters T T M It indicating one part and the letters TZ m n the other part. These two parts are preferably connected by a screw-joint, as shown at V in Fig. 1.

L represents the measurin g-chamber, having an inlet-port, P, communicating with the hollow stem or shank of the faucet, as seen in Fig. 1, and having also an outlet-port, It', (shown more clearly in Fig. 3.) Within the 6o chamber L a cylindrical piston, A, is arranged. This pistonis constructed to tit closely the side walls ofthe chamber, so as to form a perfectjoint therewith, and it is mounted upon the wrist K of a crank-disk, c, formed upon or secured to the end of an actuating-shaft, D. The crank-disk c is recessed in the wall of the chamber, as seen at4 H, for the purpose of preserving the close joint between the piston and the chamber.

A xed cut-off or partition, D, is located in the lower portion of the chamber, between the inlet and outlet ports, and extends up through a slot or opening in the periphery of the piston, thereby constituting a barrier to the direct passage of the liquid from the inlet to the outlet ports. The piston is chambered out back of the slot N in its periphery, as shown at D2, for the purpose of permitting its necessary play on the cut-oft' when rotated within 8o the chamber.

An ordinary packing-gland, J, is employed to prevent leakage around the actuating-shaft O, and an operating crank or handle, B2 B F, is applied to the end of the actuating-shaft, as 8 5 shown.

The operation of the faucet is as follows: Let the piston be supposed to be in position to cover the inlet-port P. Upon the operatingcrank being turned the inlet-port will be un- 9o covered and the piston will commence to move around within the chamber with its periphery in contact with the circumferential wall of the latter. As soon as` the inlet-port is uncovered the liquid will be drawn from the reservoir into the chamber L; but by reason of the tight joint preserved between the piston and the cut-off or partition D the liquid is prevented I the piston.

from passing directly to the outlet-port R'. When the piston nears the eotnpletion ot" its first rotation lt passes the outletport l, and, entering upon its seeond rotation, moves past the inlet-port and gradually draws in another charge ot' liquid behind it-i'.e., behind its peripheral contaet-surtaee-while at the same time it gradually t'oreesout the measure ot' liquid drawn in b vits tiist rotation, and which is itl front ot` its said peripheral eontaetsurt'aee.

1t will he seen that the eontents oi` the space comprehended between the e.\'lindrieal piston and the walls ot' the ehalnlier between the inlet and outlet ports eonstitute the Ineasure of liquid diseharged at eaeh rotation ot' The size of sueh spaee can, ol'

course, be regulated at pleasure, so that a gill, two gills, or an \Y other given quantity may bc discharged at eaeh eomplete turn ot' the operatitlg-crank. 'lhe operating-erauk is intended to be so arranged with respeet tothe actuating-shaft and piston that when said cranlv is turned down the piston will eover the discharge-port and prevent leakage; but, to still further provide against leakage, an ordinary gate, S, ma v be employed.

To indicate the amount oll liquid drawn through the l'aueet, a well-known registering device is used, consisting ot' a prong or pro- 3o jection on the handle adapted to engage with one of a series ofeogs or lingers on an indexwheel, S V', at each revolution ot' the crank.

I claim as my inventionl. In a measuring-faucet, a circular chamber provided with inlet and outlet ports, a cylindrieal piston rotating eccentrically Within such cluimber, with its periphery in sliding contact with the circumferential wall thereof, and a tixed positive cut-ott located between the inlet and outlet ports of the chamber and extending into a recess or slot in the rotating piston, t'or preventing the exit of the liquid until measured and regularly delivered by the rotating piston, substantially as described.

i2. ln a measuring-faucet, a rotating piston mounted upon the wrist of a crank or crankdisk on an actuating-shaft, substantially as described.

3. lu a measuring-faucet, the combination of the actuating-shaft, the crank-disk, and its wrist with the cylindrical piston and the ehamber having the, recess in its side wall for the aceommodation ofthe crank-disk, substantially as described, for the purpose specified.

In testimony that I claim the foregoing as my invention l have hereunto set my hand and seal this 11th day of January, 1879.
